  • Shiny Geranium (Geranium Lucidum)
    KING COUNTY NOXIOUS WEED ALERT Shiny Geranium Class B Noxious Weed: Control Required Geranium lucidum Geranium Family Identification Tips • Low-growing annual with tiny, pink, 5-petaled flowers that grow in pairs on short stems • Leaves shiny, round to kidney-shaped with 5-7 lobes • Sepals keeled • Stems reddish, smooth (hairless), up to 20 inches tall • Seeds form in capsules with a long, pointy “crane's bill” Biology Reproduces by seed. Seeds are forcefully ejected when ripe, helping it spread up as well as out from parent plants. This is probably why this plant can be found in crevices of tree trunks or spreading up hillsides. Usually grows as an annual but some plants live for two years. Flowering is from April to July and seeds mature and spread usually from late June Ben Legler by Photo to early July. Seeds germinate mostly in late summer to early fall, but can Look for pairs of tiny pink flowers, germinate several times a year. winged sepals with “keels”, and shiny, rounded, lobed leaves. Impacts Can invade and overwhelm high quality native habitat in forests and grasslands. Spreads quickly by seed and forms dense carpets, excluding other vegetation. Contaminates nursery stock and can be accidentally introduced to landscaped areas and restoration sites. Distribution Introduced from Europe and Asia. In the Pacific Northwest, most abundant in Oregon in the Willamette Valley and the Portland area. Also increasingly found in many counties of western Washington. In King County, it is found in both urban and rural areas in yards, woodlands, roadsides and spreading from landscaped areas.

  • HERB ROBERT (Geranium Robertianum) of the Geraniaceae Family Also Known by the Names of - Herb Robertianum, St
    HERB ROBERT (Geranium Robertianum) of the Geraniaceae family Also known by the names of - Herb Robertianum, St. Robert, Storkbill, Cranesbill, Red Robin, Fox geranium, St. Robert’s Wort, Bloodwort, Felonwort, Dragon’s blood. This list of common names gives a rather vivid description, of a small plant that I have come to revere, and it is always welcome, in my garden. Description Annual, to 30-40cm, stems branch in many directions, and these stems may turn red, in colour. Green leaves, 6cm long, form opposite, at knotted joints in the stem; leaves are palmate in shape, deeply cut, and often tinged with colours of pink, red or bronze. Stems and leaves are covered with very fine hairs. Very dainty, bright-pink, ‘joy giving’ flowers, 15mm across, have five, rounded petals. Each petal has 3 streaks of white, starting at the centre and phasing out along the petal. Flowers develop, in groups of 2 or 4, at leaf axils. The base of the blossom quickly fills out, develops into the oval seed receptacle, 17mm long, and when mature, looks like a bird’s beak, which is why the plant has been given the common names: ‘storkbill’ and ‘cranesbill’. As the seeds dry off, nature has a way of dispersing: by opening the ‘beak’ and ejecting with a sudden spring action, flinging the 5 small, oval seeds in five directions, ensuring that there will be future generations of the plant, for mankind’s use. I believe this plant should be in every garden, ready for service. Propagation is by seed. Plants thrive in shady, damp places, growing very quickly, flowering profusely, and self-seeding readily: if the seed is not picked, before it is dry.

  • Cynoglossum Officinale L
    United States Department of Agriculture NATURAL RESOURCES CONSERVATION SERVICE Invasive Species Technical Note No. MT-8 January 2007 Ecology and Management of Houndstongue (Cynoglossum officinale L.) by Jim Jacobs, NRCS Invasive Species Specialist, Bozeman, Montana Sharlene Sing, Assistant Research Professor, Montana State University, Bozeman, Montana Abstract Houndstongue, Cynoglossum officinale (Boraginaceae), is a biennial or short-lived perennial originating from montane zones in western Asia and Eastern Europe. Houndstongue reproduces by seed only, and was probably introduced to North America as a grain seed contaminant. This species was first reported in Montana from Sweet Grass County near Big Timber, Montana in 1900. As of 2006, houndstongue has been reported in 35 of Montana’s 56 counties (http://invader.dbs.umt.edu). Houndstongue invades grasslands, pastures, shrublands, forestlands, croplands and riparian areas, and is an effective competitor that readily displaces desirable species, establishing monocultures and further degrading forage quality in disturbed habitats. This species is particularly well adapted to invading and dominating forest openings created through logging activities. Houndstongue has a number of biological characteristics that contribute to its invasiveness. Houndstongue seeds are covered with barbed prickles that have been referred to as ‘nature’s Velcro®. These facilitate the effective, widespread dispersal of seeds on the fur, wool or hides of passing wildlife and livestock, and on the cloths of humans. The seeds are also relatively large; this provision of stored energy confers a significant competitive advantage due to high germination rates and seedling establishment. The large taproot developed in the first year of growth enables houndstongue to tolerate environmental stress and produce many seeds in the second year of growth.

  • Mountain Plants of Northeastern Utah
    MOUNTAIN PLANTS OF NORTHEASTERN UTAH Original booklet and drawings by Berniece A. Andersen and Arthur H. Holmgren Revised May 1996 HG 506 FOREWORD In the original printing, the purpose of this manual was to serve as a guide for students, amateur botanists and anyone interested in the wildflowers of a rather limited geographic area. The intent was to depict and describe over 400 common, conspicuous or beautiful species. In this revision we have tried to maintain the intent and integrity of the original. Scientific names have been updated in accordance with changes in taxonomic thought since the time of the first printing. Some changes have been incorporated in order to make the manual more user-friendly for the beginner. The species are now organized primarily by floral color. We hope that these changes serve to enhance the enjoyment and usefulness of this long-popular manual. We would also like to thank Larry A. Rupp, Extension Horticulture Specialist, for critical review of the draft and for the cover photo. Linda Allen, Assistant Curator, Intermountain Herbarium Donna H.

Geranium robertianum L., commonly known as Herb Robert or Red Robin, is a spontaneous, herbaceous plant that has been used for a long time in folk medicine of several countries and in herbalism’s practice for the treatment of a variety of ailments. Herein, we present a comprehensive review on the phytochemical characterization and the biological activities of this species, which, accompanying the remarkable increase of its use in herbal medicine, has been disclosed in the literature mainly in the last decade. The phytochemical characterization of G. robertianum has been focused mostly on the investigation of solid-liquid extracts of the plant, with special emphasis on phenolic compounds, particularly flavonoids.

  • Geranium Robertianum L
    WRITTEN FINDINGS OF THE WASHINGTON STATE NOXIOUS WEED CONTROL BOARD (NOVEMBER 1997) Scientific Name: Geranium robertianum L. Common Name: herb Robert, Robert geranium Family: Geraniaceae Legal Status: Class B (a) regions 3,4,6,7, 9,10 Description and Variation: Geranium robertianum is both a winter and a spring annual. The leaves are deeply dissected and light green in color. In late fall the foliage turns red. The stems fork, and are brittle at the joints, they are pubescent and under high light conditions are red and up to 25 cm in length. The roots are shallow. The pink flowers are perfect with five petals that are 7- 10 mm. The receptacle is enlongated into a structure called a “torus”. The fruit is a capsule. Seeds are brown and about 2 mm in length. Propagates by seed A distinguishing characteristic of the species is the pungent odor of the crushed leaves. Economic/environmental importance: Detrimental: Geranium robertianum poses a threat to forest understories and plant biodiversity by displacing native species, especially herbaceous species. In preliminary research in western Washington it was found that under 90% canopy cover it was possible to find 250 plants/m2. In a more open canopy (e.g., 50% - 60%) there were only 112 plants/m2 but these plants were larger and more vigorous. There are unsubstantiated reports that its strong odor may trigger asthma attacks (Tisch 1992). Beneficial: Herb Robert is an ornamental species and has been sold in nurseries in the Pacific Northwest and elsewhere. White flowered forms are also sold. It has a long history of medicinal use including relief from toothaches and nosebleeds (Bath and Jones 1994).

  • Obdiplostemony: the Occurrence of a Transitional Stage Linking Robust Flower Configurations

E-mail [email protected] Received: 17 July 2015 Returned for revision: 1 September 2015 Accepted: 23 December 2015 Published electronically: 24 March 2016 Background and Aims Obdiplostemony has long been a controversial condition as it diverges from diploste- mony found among most core eudicot orders by the more external insertion of the alternisepalous stamens. In this paper we review the definition and occurrence of obdiplostemony, and analyse how the condition has impacted on floral diversification and species evolution. Key Results Obdiplostemony represents an amalgamation of at least five different floral developmental pathways, all of them leading to the external positioning of the alternisepalous stamen whorl within a two-whorled androe- cium. In secondary obdiplostemony the antesepalous stamens arise before the alternisepalous stamens. The position of alternisepalous stamens at maturity is more external due to subtle shifts of stamens linked to a weakening of the alternisepalous sector including stamen and petal (type I), alternisepalous stamens arising de facto externally of antesepalous stamens (type II) or alternisepalous stamens shifting outside due to the sterilization of antesepalous sta- mens (type III: Sapotaceae).
